The Gyrodyne QH-­50 DASH (Drone Anti-­Submarine Helicopter) was a small, drone helicopter built by Gyrodyne Company of America for use as a long-­range anti-­submarine weapon on ships that would otherwise be too small to operate a full-­sized helicopter. It remained in production until 1969. Several are still used today for various land-­based roles.
